Battery Diagnosis Validation Using Container Door Status
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery diagnosis technologies suffer from misdiagnosis due to changes in battery state values caused by opening and closing the container door during charging and discharging processes, leading to unreliable diagnosis results.
Innovation Solution
A battery diagnosis apparatus that verifies the validity of diagnosis results based on the status of the container door, correcting battery state values if necessary, and generating a final diagnosis result only when the door is closed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If battery state values are monitored during charging and discharging to diagnose abnormalities, then diagnosis capability is improved, but misdiagnosis occurs when container door is opened or closed due to temperature change or physical shock
Solution Approach 1:
The system performs preliminary action by checking the door status before conducting battery diagnosis and identifying whether the door was opened during the diagnosis period. This preliminary identification of door opening events allows the system to pre-filter or pre-correct diagnosis results before final evaluation, preventing misdiagnosis caused by environmental changes.
Solution Approach 2:
The system implements feedback by continuously monitoring door status information and using this information to validate or invalidate diagnosis results. When the door is detected to be opened during diagnosis, the system feeds back this information to reject or re-evaluate the diagnosis result, thereby improving diagnosis reliability by eliminating false positives caused by environmental disturbances.
2Measurement precision
If door status verification is added to validate diagnosis results, then diagnosis accuracy is improved, but system complexity increases due to additional monitoring requirements
Solution Approach 1:
The control unit performs multiple functions: it not only controls battery charging and discharging but also monitors door status, identifies door opening events, and validates diagnosis results based on door status. By integrating these diverse functions into a single control unit, the system avoids adding separate monitoring devices and reduces overall system complexity while improving diagnosis accuracy.
Solution Approach 2:
The system uses its existing control unit to self-monitor door status and self-validate diagnosis results without requiring external monitoring equipment. The control unit leverages its existing computational resources to perform door status verification and diagnosis validation, eliminating the need for additional dedicated hardware and reducing system complexity.

AI summary
A battery diagnosis apparatus located within a battery system may include at least one processor; and a memory configured to store at least one instruction executed by the at least one processor. The at least one instruction may include diagnosing whether a battery is abnormal based on at least one battery state value during a process of charging and discharging the battery; generating a first diagnosis result when an abnormality occurs in the battery; verifying validity of the first diagnosis result based on whether a door provided on a container accommodating the battery is opened or closed; and outputting the first diagnosis result as a final diagnosis result when the first diagnosis result is determined to be valid.
